Answer:
This is the form of a circle. Use this form to determine the center and radius of the circle.
[tex](x - h) {}^{2} + (y - k) { }^{2} = {r}^{2} [/tex]
Match the values in this circle to those of the standard form. The variable r represents the radius of the circle, h represents the x-offset from the origin, and k represents the y-offset from origin.
[tex]r = 7[/tex]
[tex]h = 0 [/tex]
[tex]k = 0[/tex]
The center of the circle is found at (h,k)
Center: (0,0)
These values represent the important values for graphing and analyzing a circle.
Center: (0,0)
Radius: 7
